Crystals Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 50 Ohm ESR and 18 pF load capacitance. Confirm the package type is HC-49/US surface mount variant rather than through-hole. Ensure the operating temperature range of -10°C to +60°C aligns with the target application environment requirements before finalizing procurement.

Crystals Selection Notes

Select this component when a standard 20 MHz reference is needed with moderate stability requirements. The HC-49/US SMD form factor allows for compact board layouts while maintaining robust mechanical characteristics. Consider the ±30 ppm tolerance for timing accuracy needs and verify circuit drive levels do not exceed specified limits to prevent frequency shifts or damage.
